LARGE-PANE-WINDOW CLEANER.

Application filed November 2, 1927. Serial No. 230,581.

This invention relates to window cleaners and more particularly to such as are adapted to cleanse plate glass or other windows having large panes. I

One of the objects of the invention 1s to provide an apparatus which may be securely attached to a window sash at its top and bottom, so that the entire surface of the pane is accessible for the cleaning operation.

A further object is to provide a pairv of guides arranged vertically and on which are mounted slides carrying a moisture supplying device and also wipers for thoroughly eradicating any accumulations from the pane.

It is a further feature to provide a gutter associated 'with the device, whereby the accumulations and excessive moisture are received, preventing flooding or wetting of the premises.

These objects are attained by the novel construction and arrangement of parts, hereinafter described and shown in the annexed drawing, forming a part thereof, and in which:-

Figure 1 is a perspective view showing the application of the device to a common window sash.

Figure 2 is a sectional view taken 22 of Figure .1.

Figure 3 is a transverse sectional view of the water supplying device in a closed position.

Figure 4 is a similar view of the same, showing the control tube arranged to dispense water from perforations therein.

Figure 5 is a partial perspective View of one of the wipers and its supporting means.

Figure 6 is a perspective view of one of on line the slides, carrying the moisture tubes and wipers.

In the drawing, the numeral 10 designates in general the sides of a conventional window sash and 11 the upper and lower transverse members thereof.

A pane is designated by the numeral 12, the same being held in the sash as in ordinary glazing, as indicated in Figure 2.

A pair of sheet metal strips are bent to embrace the upper and lower sash members 11, these strips consisting of hook-like ele ments 14 at the ends of the strips, which are extended over the element 11, as at 15, to be again bent at right angles, as at 16, extending towards each other, beyond the sash frame members, where they are contracted and shaped to form cylindrical bars 17, the same passing through angle members18 at the top and bottoinof the window, where they are provided with encircling compression springs 19, held in position bypins 20, the effect being to resiliently extend the angle members 18, which are attached to the ends of vertical guide bars 21 arranged closely adjacent the side elements 10 of, the sash.

Mounted, to freely move on the guide bars 21, are slides 22 having rectangular bent portions 23 to embrace the outer side of the bars and rear-reaching portions 24pm vided with perforations 25, through which pins or screws may be passed to secure brackets 27 formed at the ends'of backing strips 28, these backing strips being slotted to longitudinally receive a wiper 29.

A similar bracket may be used in the lower openings 25 to carry another backing receptive of a shorter wiper, as indicated at 30.

Horizontal, forward extending flanges 31, formed on the slides, act as abutments to receive the thrust of compression springs 32, by which the slides are normally held ina raised position.

Mounted on the slide elements 22, just above the flanges 31, is an inner tube 32 having a plurality of perforations 33, this tube having its ends closed and provided, with a filling plug 34, by which water may enter.

Closely encircling the tube 32 is a control or valve tube 35 lixed to the slides and provided with loops 36 through which is threaded a cord 37 its ends being provided with handles 38.

Extending out through a slot 39, in the fixed outer valve tube 35, is an arm 40, the outer end of which is connected to the bight of the cord 37,'so that upon pulling the handles, the inner tube may be partially rotated, so that the perforations 33 may be brought into register with the perforations 41 in the outer fixed tube and encircling these tubes, is the bight of another cord 42, provided at its lower end with a handle 43,

by which the slides are moved downward on the guide bars against the effect of the springs 32, which return the slides to their uppermost position upon release of the handle 43.

In operation, the inner tube having been filled with water or a soapy solution through the opening 34, the device is ready to operate, and it will be understood as it is drawn down by the handle 43, the perforations having been brought into registration by the cord 37, the water will issue and moisten the adjacent pane; at the same time, the wiper element 29 will be pressed upon the pane, cleansing the same.

The water and accumulations eventually find their way into a gutter 44, attached to the lower clamp element 15 to extend below the window sash, this gutter being provided with a discharge port 45.-

From the foregoing, it will be seen that a device has been disclosed ca able of cleaning the entire surface of a in 1 size window pane in an easy and expeditious manner and without danger to the operator.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A window washing apparatus comprising pairs of upper and lower clamps to engage the top and bottom of a sash, resilient means for drawing the clamps into operative engagement, vertical guide bars carried at the adjacent ends of said clamps, slides operable on said guides, a wiper carried by said slides, and controllable means for spraying liquid, adjacent said wiper.

2. A window washing apparatus comprising pairs of upper and lower clamps to engage the top and bottom of a sash, guide bars extending vertically between said clamps, slide brackets movable on said bars, a tube fixed to extend between said brackets movable on said bars, a tube fixed to extend between said brackets to move therewith, said tube having perforations on the side adjacent the window, a second tube rotatable within the fixed tube, said second tube to carry liquid and provided with perforations registrable with the perforations in the outer tube, means for manually causing the perforations to register, a rubber scraper carried above said tubes parallel therewith, and means for manually actuating said slide brackets on said bars.

In witness whereof I have affixed my signature.
